In the protein quantification experiment, the absorbances of number of known and unknown protein samples is being measured. According to Beer's law, which of the following is proportional to the measured absorbance of the samples?
Select one:
a.
The colour of the proteins in solution.
b.
The concentration of protein in solution.
c.
The slope of the standard curve
d.
The amount of liquid in the cuvette.
b.
The concentration of protein in solution.
The correct answer is: b. The concentration of protein in solution.
According to Beer's law, the absorbance of a sample is directly proportional to the concentration of the substance being measured. In this case, the substance being measured is the protein in solution. Therefore, the measured absorbance of the protein samples will be proportional to the concentration of protein in solution.
